Political connections and preferential access to finance: The role of campaign contributions

Using novel indicators of political connections constructed from campaign contribution data, we show that Brazilian firms that provided contributions to (elected) federal deputies experienced higher stock returns than firms that did not around the 1998 and 2002 elections. This suggests that contributions help shape policy on a firm-specific basis. Using a firm fixed effects framework to mitigate the risk that unobserved firm characteristics distort the results, we find that contributing firms substantially increased their bank financing relative to a control group after each election, indicating that access to bank finance is an important channel through which political connections operate. We estimate the economic costs of this rent seeking over the two election cycles to be at least 0.2% of gross domestic product per annum.     

Accounting irregularities,management compensation structure and information asymmetry

The discovery of accounting irregularities is an important negative event for a company. The restatement resulting from the irregularity represents an average of 364 per cent of net income for the 152‐firm sample and the irregularities are predominantly revenue enhancing. The irregularity firms exhibit both lower transparency and visibility compared to a matched sample of non‐irregularity firms. Furthermore, prior to the announcement, these firms experienced poorer operating performance and their executive compensation structure is found to be significantly more equity‐based. Therefore, firms that have greater opportunity and incentive are shown to be more likely to commit accounting irregularities.     

Do Goodwill Impairments by European Firms Provide Useful Information to Investors?

In 2004 International Accounting Standards Board. (2004). International Accounting Standard (IAS) N°36: Impairment of assets. London: Author. [Google Scholar], the IASB adopted the mandatory annual impairment-test-only of goodwill (IAS 36) instead of amortization of goodwill. We present and discuss the academic literature regarding the association between the goodwill impairment, under this new standard, and the revision of investors’ expectations about a company’s future cash flows. The academic literature highlights that, in some specific cases, IAS 36 may help investors to revise their expectations. More precisely, goodwill impairment seems relevant when: (a) there is strong asymmetry of information between managers and investors, (b) managers disclose detailed information in the notes regarding their own assumptions about future cash flows, and (c) managers do not manage earnings and provide reliable information to investors. In many cases, goodwill impairment is probably useless for investors because they are able to revise their expectations based on public information, or because they cannot trust the accounting numbers and additional information in the notes about the impairment test, which are provided by (undisciplined) managers. More research is, however, needed to understand in which circumstances impairment-test-only is more useful, as well in which cases it is less adequate. Our analysis relates to the current post-implementation review and should be useful to standard-setters. Before any modification, we argue that standard-setters should carefully consider the economic and the institutional contexts when issuing a new accounting standard.     

The Changing International Transmission of Financial Shocks: Evidence from a Classical Time‐Varying FAVAR

We study the changing international transmission of financial shocks over the period 1971–2012. Global financial shocks are measured as unexpected changes of a U.S. financial conditions index (FCI), developed by Hatzius et al. (2010). We model the FCI jointly with a large international data set through a time‐varying parameter factor‐augmented VAR and find that financial shocks have a considerable impact on growth in the nine countries considered. Moreover, financial shocks during the global financial crisis are found to be large by historical standards. They explain approximately 20% of GDP growth variation on average over 2008–9, compared to an average of 5% prior to the crisis.
